[Phylogenetic relationships among some Chinese genera of Phoridae based on mitochondrial 12S and 16S rRNA gene sequences].

The phylogenetic relationships among 14 Chinese genera of Phoridae were reconstructed based on concatenated sequences of the mitochondrial 12S and 16S rRNA genes using maximum parsimony, maximum likelihood and Bayesian methods. The alignment of the concatenated sequences spanned 819 sites including 277 variable sites, of which 200 were parsimony-informative. The sequences showed a 77.7% A+T bias. The phylogenetic analysis showed that the Phoridae was monophyletic. It was shown that the involved genera in the study clustered into monophyletic Phorinae and Metopininae. The genera Diplonevra and Dohrniphora were closely related to each other. The relationships among Anevrina, Conicera and Spiniphora were also closer. The genera Metopina and Puliciphora proved to be reciprocal sister group and the cluster analysis showed the close relationship between Gymnophora and Phalacrotophora.
